To add the Cranberry element I would keep to this Alcoholic/non-alcoholic ratio. My suggestion is
1 part Gin, 1 part Cranberry juice, 2 parts Ginger Ale (perhaps with a slice of lime)
To pull it away from being “Mule-ish” - 1 part Gin, 2 parts Cranberry, 1 part Ginger Ale
Actually, this appears to be a variation of a Cape Codder, not a London Mule, substituting gin for the vodka and adding a splash of ginger ale. The traditional raios are 1 1/2 oz. of vodka and 5 oz. cranberry apple juice. When trying to replicate the Delta Signature Sunrise cocktail, I'd start with 1 1/2 oz. of gin, 4 1/2 oz. of cranberry apple juice and 1/2 oz. of ginger ale and adjust the proportions until it tastes to my liking.
